Six novel complexes of formula [Ln(pfpr)(3)](3)(NITF)2 . nH(2)O, where
Ln = Nd, Gd, Dy, Ho, Er, Y; pfpr = pentafluoropropionate; NITF = ryl-
4,4,5,5-tetramethylimidazoline-1-oxyl-3-oxide, and n = 6 (for Nd); 1 (
for Dy); 2 (for Y); 0 (for Gd, Ho and Er), have been synthesized. Thes
e complexes were characterized by elemental analysis, IR, electronic s
pectra, molar conductances. The variable temperature (4-300 K)magnetic
susceptibility of the complex [Gd(pfpr)(3)](3)(NITF) was determined.
